Abstract

L'invention concerne des anticorps humanisés spécifiques pour l'antigène pre-S1 de surface de HBV, qui montrent une affinité similaire à l'anticorps monoclonal de la souris, ainsi qu'une immunogénicité remarquablement diminuée, étant donné qu'ils possèdent moins de résidus aminoacides dérivés de la souris. Ces anticorps humanisés peuvent, de ce fait, être utiles pour la prévention de l'infection par HBV et pour le traitement de l'hépatite B.
